Superconductivity was discovered in 1911. Due to the greatly potential applications of superconducting materials and superconducting techniques, researchers from physical, chemical, and materials sciences have been working hard to achieve new superconducting materials with high superconducting transition temperature and even up to room temperature. Meanwhile, the surface/interface issue in superconducting materials has been paid more and more attention. In this paper, a brief summary is made about the previous works on the surface adsorption of copper-oxide superconductors. Then, interface effect is introduced and demonstrated to play an important role in increasing transition temperature and clarifying the superconductivity mechanism in superconducting films. The importance of the surface/interface effect is largely highlighted in the research and development of the superconducting materials.

Key words: superconductivity, oxide superconductor, superconducting film, surface adsorption, interface effect
